Carboxylic acids (not including proteins) in databases

Carboxylic acids are tough to analyze. Hydrocarbon (petroleum) carboxylic acids are particularly tough to analyze. Of the carboxylic acids that have been saved in databases to date, there appear to be differences among databases (as expected).

So, I analyzed what was in the LIPIDMAPS database. I get the feeling this database is well-curated.

LIPIDMAPS contains 25,120 carboxylic acids with deficiencies in the 1000-2000 amu range.

I wanted to compare this number and range with that available on PubChem, but I haven't found a way to search for carboxylic acids in PubChem yet without overloading things and returning no results!

Stay tuned for updates.
